摘要

Abstract

The effect of temperature-responsive solution behavior of PNIPAM-

-PPEOMA-

-PNIPAM on its inclusion complexation with

-cyclodextrin was studied. The triblock polymer was prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization and formed inclusion complexes (ICs) after selective threading of the PEO segment of the triblock polymer through the cavities of

-CD units. For comparison

PPEOMA homopolymer was prepared and the inclusion complexation with

-CD was also studied. The ICs were prepared with

-CD when the polymer was in different conformations by changing the temperature

and the formed ICs were characterized by XRD

H-NMR

TGA and DSC. The solutions of the ICs show temperature-responsive clear/turbid transition or fluidic emulsion/gel transition depending on the concentration of the

-CD added

and the stoichiometry determined by

H-NMR and TGA indicates that the stoichiometry of EO to

-CD of the resulted ICs increases with increasing of temperature.
